    Abstract : Simultaneous Localization and Mapping (SLAM) is the crucial ability for many autonomous systems to operate in unknown environments. In recent years SLAM development has focused on achieving robustness regarding the challenges the field still faces e.g. dynamic environments. READ MORE

  4. 18. Automatic Interpretation of Ion Beam Measurements of Walls in Fusion Machines

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Daniel Lundberg; Ludvig Johansson; [2023]
    Keywords : ;

    Abstract : The purpose of this study is to investigate whether it is possible to automatically interpret theresults of Time-of-flight Elastic Recoil Detection Analysis (ToF-ERDA). And if so, find out if the automaticinterpretation is quicker and/or more accurate than the current approach that consists of manualanalysis. READ MORE

  5. 19. ATLAS-BASED SEGMENTATION OF ULTRAHIGH-RESOLUTION STRUCTURAL MR HEAD IMAGES ACQUIRED AT 7 TESLA
